Vorta

The Vorta were a humanoid species genetically engineered by the Founders of the Dominion to act as field commanders, administrators, scientists and diplomats. The Vorta saw themselves as those who "serve the Founders." Vorta have pale skin, violet eyes and elongated ears that are completely joined to the rest of the head. The Founders altered the Vorta genome to include a sense of hearing greater than that of most other humanoid races, but they have comparatively weak eyesight. Vorta are immune to most forms of poison; Weyoun once observed that this trait "came in handy as a diplomat". The Vorta joined the Coalition of Independent States and the Hegemony of Independent States.
